Overview
Pathophysiology
Gross Pathology
-
A gelatinous tumor is attached by a narrow pedicle to the atrial septum. The myxoma has an irregular surface and nearly fills the left atrium.
-
Left Atrial Myxoma
-
Myxoma Embolus to Iliac Bifurcation: An embolized fragment of the tumor
-
Myxoma: Gross natural color (outstanding) photo of intact large left atrial myxoma with atrium and left ventricle opened in usual way
Microscopic Pathology
-
Cardiac Myxoma: Gamna Bodies: A peculiar form of fibrosis with deposition of iron pigment, identical to that seen in the spleens of patients with sickle cell anemia, is not uncommon in myxoma.
-
Cardiac Myxoma Common features at the interface with the atrial septum include lymphoid aggregates, smooth muscle bundles, and thick walled vessels which angiographically may look like neovascularization.
-
Cardiac Myxoma The extramedullary hematopoiesis seen here is present in about 7 percent of cardiac myxomas.
-
Cardiac Myxoma Glandular structures are seen in less than 5 percent of cases. In this example, they were limited to the base of the myxoma
